An alternative method consists in attaching Fig. 8 is a side view of a resilient ring placed the yarn, after the cop has been completed, by on the-spindle hub for holding the yarn, the ring means of a few close turns first at the tip of the having a series of apertures through which a cone, either on the cop itself or on the cop tube, knife blade may be inserted to cut the yarn or on a specially provided holder, which may inwound on the ring. clude a rubber ring or a spring loaded cap, the Fig, 9 shows a spindle with a hub' having a yarn being then carried along the cop, on which grooved edge to prevent unwinding when the cop it makes a few steep turns, and in some cases tube is withdrawn. a few close turns, before being carried to the Fig. 10 is a side elevation of a spindle with a foot and to the spindle itself. Another method mechanism for cutting the turns of thread on consists in carrying the'yarn back along the cop, the spindle at intervals.

hub, 6 the thread guide and i a bar carrying a number of thread guides supported by guide rods 0 and reciprocated in the direction of the spindle ams.

Referring to Fig. 1, when the cop is completed,

the thread guide 6 moves the yarn rapidly away from the cop cone to the gripping groove 3 at the foot of the cop, so that a few steep convolutions of yarn 2| are wound on the cop and the yarn is held fast in the groove by a few turns 22 therein. The thread guide 6 may be controlled manually in a manner well known in the art as explained below. The thread guide then conducts thejyarn to the concavely shaped part 5 on the spindle hub 4 and a few turns are wound here. To prevent these from-becoming unwound when the cop is withdrawn from the spindle, the edge 29 of the spindle hub 4 is either provided with a'plurality of notches 28, as shown in Figures 6, 7, or is grooved to present a rough surface as shown in Figs. 4, 5 and 9. The yarn clings to these grooves or to the roughened surface when the cop is withdrawn and the yarn is broken between the cop and the edge 23 when the cop is removed from the spindle.

Referring to Fig. 2, when the cop is completed a few close turns 23 are wound on the cop or cop tube at the tip thereof. The thread guide 8 then rapidly carries the yarn in the form of a few turns 2| to the point 3 at the foot of the coptube, where it is held fast by a. few turns 22, the yarn then passing to the spindle hub as above described.

Referring to Fig. 3, the yarn in addition to being held fast at the tip of the cop or cop tube, is also held fast in one or more places on the cylindrical part of the cop, by windings 26, this being particularly advantageous in the case of slippery yarn or thread. The yarn is then passed to the foot of the cop and thence to the spindle hub and secured by means of several convolutions, as described with reference to Figs. 1

and 2.

Referring to Fig. 4, when the cop has been wound the thread is again caused to make a few turns 2| on its way to the foot of the cop, and is then passed to the spindle hub, where it is held .by a few convolutions 25v in the manner above described. In passing from the foot of the cop tube to the spindle hub the yarn is gripped in the grooves or notches in the cop tube, so that it is prevented from slipping on.

The grip devices at the foot of various forms.

To enable the yarn wound on the hub of the of the cop may be spindle to be readily removed, said hub may,-

as previously mentioned, be provided with notches 28, and the coils of yarn may be cut by introducing the blade of a knife, as shown in Fig. 6.

This method is also-applicable with a perforated ring on the spindle hub 4, as shown in Fig. 8, the yarn being wound on this ring as shown at 2B, and the knife blade being inserted between the apertures. If desired, the perforated ring with the coils thereon may itself. be drawn oil the spindle hub. v

To remove the coils 25 from the spindle hub 4 by mechanical means the device shown in Figs. 10 and 11 may be employed. This device comprises a hopper 30 underneath the winding at 5 and communicating with a suction fan 3i. 3'! is an annular carrier for a cutter 38 slidably arranged on the spindle, said cutter engaging' in one of the notches 28 in the spindle hub. 39 is a spring disposed between the cutter carrier 31 and the spindle hub, and is adapted to restore the cutter to its normal position after operation. Arranged in front of a number 'of carriers 31 is a flanged bar 32, the vertical flange of which is provided with slots engaging the spindles. The bar 32 is carried by guide rods 33,.which are provided at their ends with teeth meshing with pinions 34 mounted on-a shaft 35. On the shaft is a lever 36, which is adapted to rotate the shaft. 40 designates the spindle bearing, ii the pulley for driving the spindle and 42 the driving shaft carrying the pulley 4i. Clockwise rotation of the shaft 35 causes the bar 32 to be moved to the right, so that all the coils 25 on all the spindle hubs are cut by the cutter 38, the cuttings dropping into the hopper 30, which are conducted away by the suction of the fan 3i.

Figure 13 shows an embodiment of the apparatus, whereby at the end of the winding of. the spool a hastened movement of the thread guide is effected for the purpose of producing a thread spiral 2i, and upon the conclusion of the spiral, for winding several turns upon the base of the bobbin tube at 9 and upon the spindle at 25. This mechanism is-fullydescribed in our copending application, Ser. No. 618,554, filed June 21, 1932.

The thread guides 6 are mounted upon a common rail orbar 53 which is carried-by toothed bars 55, shiftably mounted along the spindle axis. The movement of the bars 54 is effected by means of gear wheels 55 mounted upon shaft 58. Two chain rollers or sprockets are mounted upon shaft 5%, one of which is behind gear wheel 55 and which is connected with the chain 46, which is also fixed upon a sprocket mounted in the lever 51. Upon the shaft 58 of the sprocket is mounted a worm wheel which meshes with another worm wheel it also mounted in lever 5'8; A hand wheel 45 in the form of a ratchet wheel, having a handle 44, is mounted upon the axle of the last-mentioned worm wheel M.

The sprocket 48 shown in Fig. 13, mounted upon the shaft 56, is provided with a chain 4'! which is loaded by weight 52 for the purpose of 45a are taken out of the teeth of the ratchet 45,

to permit of the thread guide 6 being moved into any desired position with regard to the spindles, for instance a stationary position 23a. (Fig. 13) in order to wind-on a bunch 23 (Figs. 2 and 3) by simply turning the' handle of the hand-wheel 43 (Fig. 13) in order to revolve the spindles I. By continuing this movement of turning the handle and simultaneously turning also the handle 46 of the ratchet 45 in clockwise direction, the helical wheel 5i turning the helical wheel iii in such a fashion that the weight 62 causes the thread guides to be slowly traversed along the spindles I, the two combined motions will evidently cause a spiral 2i to be placed on the spool i. This formation of the spiral can be interrupted at will by the formation of another bunch 24 atany place, if for'this purpose the turning of the handle 44 is momentarily stopped whilst the turning of the handle on the hand wheel 43 continues. By subsequently turning both handles again simultaneously, the spiral may be continued until the yarn guide arrives at a point a where a bunch 22 may again be formed in the same fashion as described for the bunches 23 and 24. In a similar fashion, the handles are manipu ated in order to obtain a spiral between 1. In an apparatus of the class described, a
